Question
Determine whether this statement is true or false.Diffusion never occurs across a membrane.
Solution
The statement is false. Diffusion can and does occur across a membrane. This is a fundamental process in biology where molecules move from an area of high concentration to an area of low concentration. This can happen across a cell membrane, for example, in the process of osmosis where water molecules move across a semi-permeable membrane.
